SPARK-ARRESTER.

Specification of Letters Patent No. 13,216, dated July 10, 1855.

To all 'whom t may concern:

Be it known that I, DANIEL DEsHoN, 2d, of Vhitestown, in the county of Oneida and State of New York, have invented a new and useful Improvement in Spark-Catchers for Locomotive-Engines, &c.; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, letter A, represents the smoke pipe of a locomotive, which is attached to a section of the fire chamber B; C, is a circular piece extending around and raised a little above the top edge of the smoke pipe, and supported by pieces extending up from the edge of the pipe; this circular piece is made dishing on the under side and rounding on the upper side to nearly a half circle, and about half of its width projects each way over the top edge of the pipe; D, is a grating or net work attached to the outer edge of this projecting piece, and extending down and attached to the upper edge of a rim around a circular plate projecting from the side of the smoke pipe; these pieces-or parts together form a chamber in which the sparks are collected, on opposite sides of which are doors for the purpose of clearing this chamber out when necessary; these doors are made in the rim or flange surrounding the pipe underneath the grating and represented by letter E; F, the end of a steam pipe through which the steam passes to the fire chamber.

Fig. 2 represents a section cut vertically through the center of Fig. l, in which letter G, represents a steam chest in the fire chamber, into which steam is admitted through the steam pipes on each or opposite sides at H; this steam chest or the mouth of it where the steam escapes is tapered and the valve I correspondingly so, in order to give a proper direction to the current of steam as it escapes through the smoke pipe, and this proper direction is given by this shaped mouth or place of escapement, and may be regulated or thrown out toward the side of the pipe if required by running down the regulating plate J, more closely to the mouth of the steam chest; K, is a rod to which the valve I, and the plate J, are attached, and which is supported at the lower end by passing into the socket L, and runs up through the pipe, and is supported at the top by passing through theV cross piece M, at the top of this rod is arranged any convenient way of raising and lowering it or opening and closing the valve I, as may be required, which is done by a rod extending from the point N, to the engineers room.

Having thus described the manner of constructing and arranging the diHerent parts of my improvement the utility of it will readily be seen by observing the diiculty it overcomes. The grating for arresting the sparks is placed on the side of the pipe, thus leaving the top of it clear from obstructions to the draft and by this arrangement the proper direction is given to the steam to carry the smoke and sparks into the dust chamber the steam and smoke passing through the grating and the dust and sparks are left in the chamber which can be removed as desired. j

Having thus fully described the nature of my improvement what I claim to be my invention and desire to secure by Letters Patent is The arrangement of the deflector at the base of the pipe, and the curved flange C at the top and the gauze or grating D at the side as and for the purposes herein set forth.

DANIEL DESHON, 2D.
